Can Chili Rasbora live with Zebra Danio?
Caution — with care
Why
- Only a narrow water hardness overlap — keep both around 5–6 dGH.
- Large size gap (Chili Rasbora 0.7" vs Zebra Danio 2") — the bigger fish may eat the smaller one as they grow.
Sweet spot: both do well at 75–77°F and pH 6.5–7 — aim there.

How to make it work
